I have the clarke cl430 lathe, and still learning how to make things.

would like to get some more chucks from arceuro but they are different pcd to my lathe.

with limited equipment how do i mark out the pcd i need for other chucks?

i need to mark out 108, 84 and 66mm. clarke is 115mm

I did make one backing plate using 1" ali rd i got the clarke one's marked out then bolted it on and turned it match head on lathe.

then marked out the 108mm and drilled it but was slightly out.

managed to be able to use it as was on 4 jaw independant.

but wont get away with it for other chuck's i want.

cheers

I know that some (many) will respond to this reply along the vein of "It is good practice to make the T-Bolts", but regardless here goes……….why waste all of that time making T-Bolts and messing about with the steel specification, when all you need to do is buy them ready made from RDG, ArcEuro Trade, etc, etc, etc. Get the bolts and nuts and then spend your time making something really useful like swarf, or some really difficult component for a model train or whatever.

The real trick with engineering, model or otherwise, is to not waste time re-inventing the wheel. Make use of the effort of others and focus on the real task in hand.

Never had any bother either, get most of my stuff from ArcEuro too.

Thanks very much for your help!

The Arceurotrade tutorial is great, but they mention they use special equipment for that and suggest maybe not to do it without it.

Your other suggestions seems good, but this is not my first language and I'm only really used to smaller mechanisms of musical instruments (not like a lathe), so maybe someone has a photo or a more specific explanation? The English names of the tools/parts a bit tricky for me to understand.

Thanks again

If you go to this link: **LINK**

and look at the articles on dismantling the C3/SuperC3 mini lathes, and replacing the spindle bearings (separate article), this may tell you what you need to know.

I have a huge interest in the sten gun, as it was great example of design engineering in difficult times. No or little skilled labour available, specialist machine tools scarce, materials in very short supply and needed elsewhere for more pressing items, during the wartime panic after dunkirk.

The sten was a design masterpiece imho. It ticked all the boxes, simple to manufacture with unskilled labour, mainly housewives drafted in, in any videos or photos i have seen of production. It didn't need any fancy machine tools to make, a lathe, horizontal mill and some gas welding equipment seems to be about it. The materials needed were nothing out of the ordinary, and nothing difficult to make, plain old mild steel mainly.

It was churned out in the millions by a company any of us of a certain age will remember and be familiar with, namely Triang toys made by lines brothers in merton, london. This was the largest toy factory in europe at one time i believe.

Have you seen the video below ? Peter Laider is an expert in most british military firearms , and i think can be contacted on some of the military firearm forums.

P.s, isn't discussion of naughty things like firearms banned on here like it is everywhere else by the politically correct nazi's ?

Jack,

If you look on the ArcEuroTrade website (arceurotrade.co.uk) under "projects and articles", almost the last thing in the index, you will find some help in various jobs on the Seig lathes, including the C3/Super C3.

Hi All,

I've come across Yuriy's excellent Android DRO and have the components for the basic MSP430 version winging their way to me.

I am however, having trouble finding suitable scales in the UK. IGaging do not appear to have any UK dealers – there are odds & sods on amazon / ebay, but not in the lengths I'm after. I can't justify glass scales I only have a Dore-Westbury Mk1 mill, so 3 glass scales would probably cost as much as what the whole mill is worth!!

The digital scales that Arc Euro Trade sell look very similar to to AccuRemote scales, has anyone had any success with these scales & Yuriy's MSP430 interface? I have been touch with Arc Euro Trade, but they were unable to give me any useful information, at all.

Cheers in advance for any input (and many thanks to Yuriy for his hard work! – BTW: Have you thought of extending TouchDRO to display fractional inches…1/4, 1/2, 3/4, n/8, n/16, n/32…etc…?)

cheers

Paul,

They are the same thing (these ones are: http://www.arceurotrade.co.uk/Catalogue/Measurement/Digital-Readouts-with-Dedicated-Remote-Display). iGaging is a US distributor for various things and their "DigiMag" scales are made by Shahe, as are the AccuRemote scales.

I haven't given much though to displaying fractional sizes but you can convert from fractional sizes to decimals in the app by typing a fraction into the "preset dimension" box or any other input box. If you need to move the spindle/carriage by 1 5/6 of an inch you can type 1+1/6 into the preset box and then move the axis until it reads 0.000 and you're there.

Hope this helps

Hi Yuriy,

Many thanks for confirming that…I'll order a set up & get tinkering. The MSP430 should arrive in a day or two. I'm also interested in experimenting with a tacho sensor, too.

@Neil…I think the Android solution will get me up & running. A set of glass/magnetic scales and a (larger screened) DRO may be something to aspire to, should I acquire a larger mill that would justify the more accurate scales.

cheers

Paul

Paul,

Glad I could help.

P.S. upgrading from "iGaging" to glass/magnetic scales takes six resistors and different firmware version once you're ready

Hi Clive,

Thanks for the heads up – yes, I have – there was a mention of them earlier back in this thread.

They seem to do 3 types

• cheapest are what appear to be glorified digital callipers – no remote display – coin battery powered and no USB socket.
• next up are what appear to be basically the same scales that ArcEuroTrade sell, but explicitly branded Warco – and only available 2 in sizes (that are far longer than I'd need!)
• Finally the glass scales – about 30% more expensive than the same product in various other places.

In all cases, there is no indication of the original make and/or the data encoding they employ, which is rather important if I'm to try to link them to Yuriy's piece of kit (I don't mind building Yuriy's mixed scale adapter board, if necessary)

Has anyone had any direct experience of using these or any other of the scales (from the cheaper end of the market!) bought from UK sellers with TouchDRO?

cheers

Does anybody know if Arc Euro Trades ‘ER25 Lathe Collet Chuck – 100mm Dia – 72mm Register’ will fit on to my Warco WM180 lathe (without modifications)? Reading the description is sounds like it will, but I was wondering if anybody has tried it?

David

Hello David,

Looked at the Warco WM180, and noted that it is fitted with a 100mm chuck. 'Most' Chinese origin 100mm 3-Jaw Self Centering chucks have a register of 72mm. This is general Chinese standard. So in theory, ARCs ER25 Lathe Collet Chuck -100mm Dia, – 72mm Register will fit in place of the 100mm 3-Jaw S.C. chuck currently fitted to your lathe. Best way to be sure is to remove the chuck and measure the register. If register is 72mm, it will fit.

Ketan at ARC.

[MM57Participant @mm57]

I just happen to be sitting here caressing(!) what appears to be that exact collet chuck and a 100mm Myford backplate that arrived from Arc Euro yesterday (plus a ball bearing collet nut).

You need to cut the register in the backplate and, if is is the same one, 3off 8mm clearance holes on a 84mm PCD – and supply the 8mm bolts yourself

Seems good quality components but I've had to take about 0.050" off the thread (in the backplate) from the inner end of the bore as it was stopping the backplate going right back onto the face of the spindle register. The plate was about .002" off round/centre on my ML7, but now it's bob-on after a small skim and a polish. Cutting the register tonight….

[Jon GibbsParticipant @jongibbs59756]

In my ML7 have tried end-mill holders which are the cheap and cheerful solution…

**LINK**

…but these need a draw-bar and can be a bit of a pig to remove too, as others have said.

I would recommend making yourself a dedicated ER32 collet chuck though, as others have said.

Harald Hall has instructions here…

…and I can thoroughly recommend them. You just need to buy the collets, nut and spanner to fit from somewhere like Arc…

[Les Jones 1Participant @lesjones1]

Hi clogs,
I do not know exactly what you mean by a "collet holder" Arc Euro sell MT3 collets on this page and an MT5 to MT3 sleeve here. I think a better solution would be one of the ER lathe collet chucks (as each collet covers about a 1mm range of sizes.) and make a backplate to mount it on the spindle in the same way as a normal chuck or faceplate is fixed. Other suppliers probable also supply these items. I have bought these type of items from Arc Euro so I knew where to look in their online catalog.

[Ketan SwaliParticipant @ketanswali79440]

Hi Bazyle,

I saw the 1 star treatment too

I don't know why those reviewers had that experience. I can only qualify the experience I have had as follows:

1. When I first started attending the shows – about 10+ years ago, I didn't know anything about protecting the machines overnight and in transit/storage pre and post shows. I watched the competitors spray their machines with WD40 at the end of shows for the onward journeys back home. So, I did the same. Nice and cheap. On one occasion, I left the machines overnight in the Luton, as it was cold and wet outside, and I didnt fancy offloading at night in this weather. In the morning took the machines out to put back into our display. Removed the transit shrinkwrap, and still saw some rust film on exposed surfaces. Some expletives later, cleaned and oiled the machines. My team and I have many such experiences with WD40. Finally, Paul Price from Shield came along and introduced us to Metalguard Ultra, which initially we regarded to be an expensive gimmick. We proceeded to try it and found it worked. This was also used as part of our preparation service when we used to offer it. As soon as machines were prepared, we sprayed them with the metalguard to avoid transit rust, be it to destinations in U.K. or Europe, because we had no idea of transit/storage conditions. We even suggested it to SIEG, but they considered it to be too expensive for transit protection. they preferred the white grease or red grease (lovingly referred to as chicken fat)

2. Originally before we discovered metalguard, we had to regularly clean our display machines and wipe the tables with oil soaked rags at least once a week, depending on how many visitors had been and touched them. Once we started using metalguard, we clean our machines once every two odd months or if needed, followed by a fine mist treatment with metalguard. Before, rusty figures were quick to form marks on exposed surfaces. I admit that the temperature is above 17 deg.C, but still, rusty figures are rusty fingers. For colder temperatures the user might have to clean/apply metalguard more often maybe, depending on various factors, but in my opinion, this stuff protects far better than WD40, for sure. As the spec. on Shields site says: it complies with defence and NATO standards. We have been using it now for well over seven years, and we are happy with it.

This product had also been well tested by one of the largest specialist woodworking tools companies in Germany over an extensive period before they got the confidence and comfort to buy it from Shield and sell it. Their purchase volumes from Shield are very high.. Similarly, their sales into USA have also grown over time.

Initially, we were the only main U.K. seller for their product. Then Axminster came on the seen, purchased from them and our sales for this product reduced by 50%. A year later, machine-dro started stocking SHIELDs product to complement their Ultrasonic tanks related product range, resulting in a further drop in our sales. We are in business to make money, just as SHIELD and others are. If the quantity of sales become nonviable, as they did at the time, it is difficult for us to invest in advertising and promoting their product in the way we did at the time, pre the competitors. We had certain verbal agreements at the time which failed, resulting in the commercial decision to drop the product at the time. Our and SHIELDs position today is different to how it was for both of us at the time we dropped their products.

Whatever the commercial reasons, I am still comfortable that their products work. Their products are much more popular now, and I feel that too speaks volumes and should be taken into consideration, if we are to make any judgement on quality….and they hardly do any advertising or marketing of their own. SHIELD is a small British business which has come a long way.

They also do a wax polish which works.

At the end of the day, we all have our own experiences.

These boys seem to be one of the main suppliers in the States for BP parts. It's helpful to know that "ABEC7" refers to the level of precision – I've learned something useful today!

The ABEC7 bearing kit seems to be $325 from them and there's a vid showing how to fit them. Can't say I'm massively impressed by the state of their workshop and their advice for setting the nut is "knock it pretty tight". Presumably that's a technical term. I love the way he "cleans" his hands at 4:55! I'm not convinced Ron Dennis would offer him a job.

All in all, it doesn't look too tricky if you can figure out how to drive the bearings on and off. I'd love to hear how you get on.

Murray

Hi Murray,

Americans like ANSI, and Europeans like ISO. So, ANSI ABEC7 = ISO P4.

Most common contact angle for match pair super precision angular contact bearings is 15 Deg. which is designated by the letter 'C' after the bearing number.

So, if JS is correct about what was fitted to the original Bridgeport, '7207CTRDULP4', then the letter C in this code means 15 Deg. contact angle, DU = duplex matched pair, L = suitable for light preload, P4 = ABEC7 precision.

NACHI – JAPAN price for the match pair 7207CDUP4 = same as above reference number = RHP/NSK reference number for the above = or better than SKF quality….probably…, currently GBP115.00 including VAT, delivered U.K. Mainland for the NACHI brand.

In the super precision match pair world, SKF by brand is 'less regarded with desirability' than others….in our opinion.

Ketan at ARC

Edited for clarification of brands/quality, and price indication specifically for NACHI brand at time of writing.

[Euan MacKenzieParticipant @euanmackenzie50767]

Many thanks for all the helpful comments: as to method of measurement, I put a 3MT precision lathe test bar (brand new from LPR Toolmakers) in the SX3's 3MT spindle, and rotated it (in tapping mode), against a DTI; which showed 3 thou runout. I know the 3MT test bar is OK, because I recently had my Hercus Model C lathe (a clone of the South Bend Model C) restored by F. W. Hercus, here in Adelaide, and no run out is detectable in the Hercus (3MT) headstock.

When the weather is cooler, I will repeat the test using an Allen key to rotate the spindle by means of the drawbar, instead. Also check whether the spindle has any detectable side play in the bearings.

As regards the table, I mounted the DTI in the SX3's drill chuck and wound the table from full left to full right; it is flat to better than a thou from LHS to about 3/4 of the way over to the RHS, where it commences to rise to 5 thou at the extreme RHS; so I don't think it's a tramming issue. Again, when it's cooler, I will repeat the test using a 3MT/ER40 chuck/collet to hold the DTI, instead.

I do have a copy of Dr Georg Schlesinger's "Testing Machine Tools", sixth edition.

I should also add that my SX3 is exactly 'as delivered'; ie I have not performed the type of work recommended by arceurotrade; who incidentally have been most helpful; although I purchased my SX3 from HAFCO, in Sydney, via General Tools in Adelaide (because I had no facilities to unload a 200kg crate). General Tools very kindly used an engine hoist to put it on my bench.

I did my machine apprenticeship at English Electrics Willans Works, Rugby, in the mid fifties; I well remember that the castings for the Fullagar Diesel engines (intended for ships, submarines, locomotives and power stations) were left outside to weather for six months, before any machining. So, I believe that my SX3 table may well have warped after machining (it has no evidence of 'hand scraping' marks, only surface grinding).
